For most automotive applications a battery needs to supply a lot of current for a short period of time to turn over the engine and get the car started. With the engine running, the car's alternator produces all the power the car needs. Thin plates inside a starting battery increase the surface area and produce this relative burst of energy. Thicker plates in a deep cycle battery provide a steady amount of current over a long period of time. Deep cycle batteries excel in reserve capacity (RC),...

HIV infections persist despite treatment that successfully decreases viral blood levels to the point where doctors can't detect the virus. But that doesn't mean the person is cured. The virus hides in the body, not replicating, just waiting for a chance to jump out of the shadows and reemerge.
If you want to appreciate the value of microbes, look no further than a chunk of cheese.

Now, thanks to microbiologists and the long tradition of cheesemaking, we know a lot more about the microbes that make our favorite types of cheese possible.
While some researchers look for drugs to treat HIV, other scientists delve deep into the virus itself for answers on how it causes infections.
The presence of certain bacteria can indicate whether the vaginal tract is healthy or not. It could also impact the likelihood of acquiring certain sexually transmitted diseases, like HIV, a new study suggests.
Gonorrhea infections reached a peak in 1975, then decreased until 2009, when infection rate started rising and has increased each year since. With the rise of antibiotic resistance, those numbers are only going to get worse — unless we find new treatments against the bacteria.

Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells. That single genetic variation increased the amount of cholesterol on cell membranes that Salmonella and other bacteria use as a docking station to attach to a cell to invade it. They also found that common cholesterol-lowering drugs protected zebrafi...
Whether your palate runs to domestic or imported, a piece of cheese can be a real treat for the senses. Its smell, taste, and texture are all parts of its appeal. A big part of what makes that savory wonderfulness comes from the microbes in and on the cheese. Thanks to a team of researchers dedicated to studying those microbes, we have a better understanding of their importance to cheese and us.
Windborne microbes shifting in the snows of the great ice sheet of Greenland may be able to neutralize some of the industrial contaminants oozing out of the melting ice.

The squiggly guys in this article's cover image are Propionibacterium acnes. These bacteria live in low-oxygen conditions at the base of hair follicles all over your body. They mind their own business, eating cellular debris and sebum, the oily stuff secreted by sebaceous glands that help keep things moisturized. Everybody has P. acnes bacteria—which are commonly blamed for causing acne—but researchers took a bigger view and discovered P. acnes may also play a part in keeping your skin clear.
